Rain? Cold chasing moisture. Def gonna have to get its act together and go neg tilt further west. What its showing now aint gonna cut it for a SC snowstorm. Even though its 84 hour nam... I know. Current run of 12z nam 925mb temps way too warm and the blow up RH @ h7 is mainly east of the 0C line & 850 low.

 

925 temps.

But its the 84 hour nam.

Extrapolating the 84hr NAM, because that is always a smart thing to do, I see no evidence of a vort shearing off to the north and east like the 0z Canadian showed. The NAM would likely close off over GA based on the neg tilt at H5. That should give at least some merit to the GFS and it's deeper look compared to at least the Canadian.

I trust your slide rule and colored pencils unquestioningly.
